HENRY W. FIORGAN, OF ROCHESTER, NEW YORK.

NAILING-MACHINE.

To all whom it may concern Be it known that I, HENRY W. MORGAN, of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Nailing- Machines; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference numerals marked thereon.

My invention relates to nailing machines, and it has for its principal object to provide a mechanism that is especially adapted for nailing together the parts of paper or paper board boxes, in a manner that will insure securely attaching the parts, without leaving any projecting or unprotected ends of the nails.

A further purpose of the invention is to afford a simple construction that can be manufactured at a minimum cost, and by which the operation can be readily and quickly effected.

To these and other ends the invention con sists in certain improvements and combinations of parts all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

In the drawings: Figure 1 is a view in side elevation of a machine constructed in accordance with a preferred embodiment of my invention, showing the boxes in position, and partly broken away to afford a view of the interior; Fig. 2 is a sectional view of one of the anvils, partly broken away, and illustrating the first step in driving the nails; view on the line 8 -3 of Fig. 2; Fig. 4: is a plan view of the anvil; Fig. 5 is a sectional view of the other anvil and its cooperating plunger, showing the final step in securing a nail to the box; Fig. 6 is a perspective view of the body portion of a box of the character for which the present machine is designed; and Fig. 7 is a perspective view of the bottom wall before it is attached to the body portion.

Similar reference characters throughout the several figures indicate the same parts.

The invention is susceptible of various applications and among other uses is designed especially for attaching together the walls of boxes made of paper, paper board, fiber, fiber board, and the like, so that they may be Specification of Letters Patent.

tightly secured, and whereby the entire operation can be very quickly accomplished. To this end, I have provided a mechanism in a unitary structure that enables the result to be effected in two operations, the nails being driven into the walls of the box so that in the finished structure the ends of the nails will be entirely concealed and protected.

In the present embodiment A designates a portion of the main frame of the machine upon which are supported a pair of anvils B, B arranged in juxtaposition to each other, these being mounted on holders C, C which are slidable upon the guides I) and adjustable by means of the threaded posts E which cooperate with threaded openings in the holders.

The anvil B is provided in its working face with a plurality of nail deflecting recesses, the purpose of each of which is to engage the pointed end of the nail as it strikes the anvil and bend it laterally upon itself in the manner shown in Fig. 2. In order that the nail may enter the recess more readily, and to insure proper deflection of the end portion, I construct each recess F so that it is widest at the nail receiving end, as designated at f, and tapered thence toward the opposite end, the width of the recess at the narrower end being slightly greater than the thickness of the nail. The depth of the recess F is such that when the nails have been driven home by the hammer, the extreme points are bent upwardly far enough to barely engage the adjacent face of the box as shown in Fig. 2. Arranged above the recesses F are the nailing chucks G which are supplied with nails in the usual manner in this class of machinery, and H designate hammers, carried upon the cross-head I which may be reciprocated in any convenlent manner.

J, J designate a pair of boxes arranged upon the respective anvils, each embodying a body portion J and a bottom portion J provided with flanges J which are adapted to engage the edges of the body portion, and to be attached by nails driven through the several thicknesses on the four sides of the box. After the nails have been driven to the position shown in Fig. 2 by the first operation, it is desirable to drive the points of the nails upwardly within the walls of the box and to flatten the lower part of the nails against the adjacent wall of the box. This function is accomplished by the anvil B upon which the box can be quickly positioned for the second operation after its removal from the anvil B.- Cooperating with the anvil B is a plunger K which may be reclprocated 1n any convenlent manner, and

for this purpose is preferably carried by the aforementioned cross-head I. Upon placing the box upon the anvil B with the nails in the position shown in Fig. 2, and lowering the plunger K until it'comes into operative relation with the anvil, the nails are clenched, causing the ends to be forced upwardly into the walls of the box, and fiattening the lower portion against the adjacent wall of the box as shown in Fig. 5.

By arranging the anvils in juxtaposition to each other, I provide an economical and simple method for driving and clenching the nails by two operations, all that is required being to shift the box from one position to the other, plished expeditiously with the means that I have described. The parts of the box are secured together in a most eflicient manner, enabling the production of a finished article that possesses sufficient strength for all re quired purposes and can be manufactured at a low cost.

I claim as my invention:

1. In a nailing machine, the combination with a main frame, of a pair of anvils supported on said frame in juxtaposition to each other, nailing chucks arranged above one of said anvils, a reciprocating cross-head mounted on the frame, a series of hammers and this can be accom-' carried by the cross-head and cooperating with said chucks, and a plunger also carried by the cross-head and cooperating with the other anvil.

2. In a nailing machine, the combination with a main frame,of a pair of anvils supported on said frame in juxtaposition to each other, nailing chucks arranged above one of the anvils, reciprocating hammers cooperating with said'chucks, and a reciprocating plunger cooperating with the other anvil.

3. In a nailing machine, the combination with a main frame, of a pair of anvils sup-' ported on said frame in juxtaposition to each other, one of the anvils having a plurality of nail deflecting recesses in its working face, nailing chucks arranged above said recesses, hammers cooperating with said chucks, and a reciprocating plunger cooperating with the other anvil. p

4. In a nailing machine, the combination with a main frame, of a pair of anvils supported on said frame in juxtaposition to each other, one of the anvils having a plurality of nail deflecting recesses which are widest at their receiving ends and tapered from their receiving ends toward their opposite ends, chucks arranged above said recesses, hammers cooperating with said chucks, and a reciprocating plunger cooperating with the other anvil.
